CLOSURE FASTENEB.

Application filed February 28. 1925. Serial No. 12,316.

T all whomt may concern.'

Be it known that I, FREDERICK 1V. PLOSS, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia 5 and State ofPennsylvania, have invented certain new and useful Improvements inClosure Fasteners; and I hereby declare that the following is a full,clear, and exact de scription thereof, reference being had to theaccompanying drawings, which form part of the specification.

My invention consists in a closure fastener for doors and moreparticularly for automobile doors and bodies. My device is a dove-tailadapted to be attached to a door jamb and to receive a projection ortongue attached to the door, in such a manner as to keep the door wellbalanced on its hinges by the resilient contact thus formed between 20the door and the door jarnb.

One advantage of my device is the type of full elliptical springs whichsurround a rubber cushion in such a manner as not to compress therubber, thus no initial compression, p

which would harden the rubber isexerted upon this resilient cushion.

Another advantage appears in the elliptical spring reinforced by rubber.This construction allows the quickly acting spring to withstand theconstant shocks to which it is subjected by the tortions to which anauto mobile door is constantly subjected. Also the shock of closing thedoor is well taken care of by the elliptical type spring, reinforced bya resilient cushion of rubber.

It has been found in practice that a long life may be expectedfromelliptical type springs reinforced by rubber.

Referring to the drawings:-

Fig. 1, is a plan view of my closureV fastener. p

Fig. 2, is a side view of my device showing the tongue 'engagedtherewith.

Fig. 3, is a cross section taken on the line 3-3 of Fig. 1.

Fig. 4, is a cross section on the line 4-4 of Fig. 1.

Fig. 5, shows a side view of the rubber cushion.

Fig. 6, shows my elliptical spring.

Referring more particularly to the drawings 10 denotes a flange of mycasing 11 adapted for attachment to a door jamb having countersunk screwholes 12. The casing has an open face 13 and an open front 14:. The case11 is provided with inwardly protruding portions 15 adapted to normallyhold the rubber cushions 16 in place.V Surrounding or encasing eachrubber cushion is an elliptical spring 17. A plate 18 having 30countersunk screw holes 19 is provided for attachment to a door, andprovided with a tongue 20 adapted to engage the springs 17 when the dooris closed.

Having pointed out the novel construction, combination and arrangementof my parts, what I wish to claim and secure by Letters Patent is 1. Ina closure fastener the combination of a casing consisting of a boxhaving an outwardly extending rim; a cover plate hav ing an openingtherein, said plate being adapted to engage said extending rim and twosprings the ends of each being adapted to virtually meet, said meetingends of each 75 spring being adapted to abut the same side respectivelyof the box.

2. In a closure fastener the combination of a casing consisting of a boxhaving an outwardly extending rim; a cover plate hav ing an openingtherein, said plate being adapted to engage said extending rim; twocushions positioned in said box; means in the bottom of said box adaptedto engage said cushions; and two springs adapted to virtually encloserespectively said cushions, the ends of each spring being adapted tovirtually meet, said meeting ends of each spring being adapted to abutthe same side respectively of the box.

In testimony that I claim the foregoing as my own, I affix my signature.

FREDERICK W. PLOSS.
